ID Tag Option:

If choosing the ID Tag the 'Auto Arm' option above can also be added & will function seamlessly with the ID Tag (Auto-Arm option can also be added if using the standard fobs, but the alarm will need to disarmed every time you want to move or use the bike - can be put into service mode so the alarm will not interfere when servicing the vehicle), the alarm will automatically disarm when the Tag is within 10 metres of the alarm unit. Please note if the alarm is armed by pressing either the standard fob or ID tag button it will also need to be disarmed using the button, it will not automatically disarm even when using the ID Tag. When using the Tag button there is usually a 3 secound delay, this is normal, when using the Tag normally there will be no such delay, there is no delay when using the standard fobs.

The ID tag & any programmable options can only be added when ordering a new Defcom3.1b, if required at a later date the alarm unit complete with all fobs will need to be returned to us for re-programming, extra charges will be incured. The TXM252 or HPA Evo fobs can be added at any time using the 5 digit override code

Free Faraday pouch when the B9.5 ID Tag is ordered, stops communication with the alarm should the tag be in a nearby area
